Amplificateur audio Omnitronic 80709752 performance/scène noir

The Omnitronic MPZ-500.6P ELA mixer amplifier is a 19"-format unit designed for both mobile and permanent ELA (electro-acoustic) sound reinforcement systems. It provides outputs for 70 V and 100 V lines as well as 4–16 Ω loudspeakers, six mixable inputs (up to 3 microphones and 3 line-level devices), a line output for connecting an external device such as a mixing console, and integrated playback from USB or SD via an MP3 player with infrared remote and blue backlit LCD.

Advantages

The MPZ-500.6P offers zoned control with six switchable front-panel zone outputs for flexible distribution of audio to different areas. A front microphone input includes an adjustable priority switch and an assignable gong for announcements with automatic, continuously adjustable level reduction of other signals. Protection features include a fan for cooling, switch-on delay, overvoltage and short-circuit protection which electrically isolates the loudspeaker outputs when triggered. The unit’s 19" format makes it suitable for rack mounting in professional and mobile setups.

How to use

Install the MPZ-500.6P into a standard 19" rack or place it on a stable surface. Connect microphones and line-level sources to the mixable inputs, and wire speakers to the appropriate 70 V/100 V taps or to the low-impedance terminals (4–16 Ω). Use the front-panel switches to assign and switch the six zone outputs as required. Insert a USB stick or SD card to play MP3 files via the built-in player, or control playback with the included infrared remote. Adjust the microphone priority and gong settings on the front panel when announcements are needed.

Recommendations

For reliable long-term operation, ensure adequate ventilation around the unit so the fan can maintain cooling, allow the switch-on delay to complete before routing audio to speakers, and follow recommended wiring practices for 70/100 V and low-impedance speaker lines to prevent overcurrent or short-circuit protection from activating.
